Do the following problems on a separate sheet of paper. Draw a picture to accompany each problem, then write your answers
1. You exert a force of 25 newtons while you move a rock 15 meters. How much work did you perform?
2. You move a box 5 meters and perform 900 joules of work. How much force did you apply to the box?
3. You move a box by exerting 45 newtons of force. The total work performed was 2700 joules. How far did you move the box? d. You exert of force of 75 newtons on a rock. You push and you
push, but you can't budge it. You are exhaustedt How much work did you perform?
4. Let's say a small person with a mass of 50 kg walks up two flights of stairs. A heavy person with a mass of 105 kg walks up the same stairs. Who did more work and why? (Hint: Remember
that a newton of gravitational force (weight) is about equal to 100 grams.)
5. You pull a wagon carrying your younger brother 1000 meters (1 km) to the store using 20 newtons of force the whole way. It takes you 15 minutes to get there. How much power did you
generate, in joules per minute? In watts
6. You and a friend move a grand plano across the living room, exerting 25 newtons of force and performing 175 joules of work. It takes you 14 seconds. How far did you move the plano? How
much power did you generate, in watts (joules/sec)?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
